Description

The invention "relates to a release binding, which has a sole holder which is movably arranged on a base body and latched in the position of use , which releases the ski boot after releasing the locking, the base body in one to the plane of movement of the sole contains ex's plane which is approximately at right angles is arranged movably on a base plate and is also locked.

It is a safety ski binding (Swiss patent 488 467) known, which can release the ski boot in two directions. This ski binding has a lifter carrier acted upon by a spring, which locks two latching elements ο one this Rastel eiaontc is used to lock the movement of the

Binding upwards, the other locking element blocks the movement the binding to the side. If an overload occurs in one direction, the associated latching element presses the bast carrier back against the force of the spring. The movement of the latching carrier also causes the latching element, that blocks the movement in the other direction, released. When arranging a single grid support, which acts on two locking elements, however, difficulties arise when coordinating the two locking mechanisms "

The invention is based on the object of creating a release binding of the type described at the beginning. in which probably only a single spring, the preload of which is expediently adjustable, acts on the latches, In which, however, "both latches are guaranteed by their own components.

This object is achieved according to the invention in that the sole holder has two latching elements, one of which in a manner known per se with one designed as a pivotably mounted control cam locking member is in engagement and the other latching element engages in an approximately curved locking member arranged on the ski.

As a result, the two Verrastimgen are separated from each other and voting can be done in a simple and easy way take place. The binding according to the invention can of course also release in the event of diagonal falls. For pure twisting falls is generally released through the front binding portion.

If the heel binding is used, it is therefore sufficient if there is a 'release in the case of a diagonal!) Smoothly if the force is at an angle of about Ί5 or more to the
Attacks horizontal.

This is therefore assumed in special training. dx; ß the cam-shaped locking member in its
Center has a recess with vertical "surfaces, the distance from one another approximately corresponds to the diameter! ^{1 of} the locking element, the depth of engagement of the locking element in the recess being equal to or greater than the radius of the locking element *

In the drawing is an exemplary embodiment of the invention shown :. Show it:

As you can see in the drawing, there is a sole holder on a base body 2 um. one across the ski and ... par all el axis 3 pivoted to the surface thereof annoys and carries two locking elements formed as "roles" 4, 5 · The distribution element 4 is used by eiiiem

in the. Base body 2 pivotally mounted and designed as a control cam locking member 6 overlapped by
a spring 8 is acted upon with adjustable bias. The other latching element 5 engages in a latching member 7 that is connected to the ski or to a base plate 10 and is approximately curved in the shape of a curve. The base body 2 can also be pivoted about an axis 9 perpendicular to the ski surface relative to the ski or relative to the base plate 10. By the two catches 4, 6 and 5, 7, the sole holder 1 is in the
shown position held.

If there is now an upward force, for example in the direction of arrow 11, the latching element 4 will push back the locking member 6 against the force of the spring 8, so
like this Figo. 4 shows. If this force is correspondingly large, the latching element 4 presses the locking member 6 in this way
far back that, as FIG. 5 shows, the sole holder 1
can pivot freely upwards about the axis 3. During this movement, the latching element 5 is also disengaged from the latching member 7, so that a lateral rotary movement of the sole holder 1 together with the. Base body 2 around the axis 9 would be possible.

V / iG especially Figo 'J can be seen, has the curved path Latching member 7 in its center has a recess 12 with vertical side surfaces, the distance between them corresponds approximately to the diameter of the locking element 5 « The engagement of the latching element 5 is somewhat deeper than the radius of the locking element itself. As a result, the binding is against a pure lateral rotation release

locked. Depending on how deep the latching element 5 engages in the recess 12, a diagonal release can take place from a certain angle of the sole holder to the horizontal. In general, the binding will be designed in such a way that a diagonal ^{release is possible from about 15 Q} to the horizontal,

If such a diagonally directed force occurs, the latching element 5 moves out of the recess 12 and also in a lateral direction, as illustrated, for example, in FIG. 6. Here, in the same way as in the case of vertical loading, the other latching element 4 presses the locking member 6 back ₅ against the force of the spring 8, as can be seen from FIG. 4-. In the event of a correspondingly large diagonal force, the latching element 5 emerges completely from the recess 12 and moves upwards and to the side on the cam-shaped latching element 7, namely until, according to FIGS. 7 and 5, the locking element 6 compresses the spring in such a way that the locking element 4 can move past the locking member 6. The binding is then freely movable around both axes 3 and 9

The invention is not limited to the illustrated embodiment. For example, the locking element 5 are adjustable on the sole holder 1, so that the depth of engagement of the locking element in the Recess 12 can be changed.
